Answer:

q = 14

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties
Complementary Angles: Angles that add up to 90°

Step-by-step explanation:

Step 1: Set up equation

The 2 angles must add up to 90°.

(4q - 5)° + 39° = 90°

Step 2: Solve for q

Combine like terms: 4q + 34 = 90
Subtract 34 on both sides: 4q = 56
Divide both sides by 4: q = 14

I don’t understand:( can someone break down the steps I have to do

Answer:

x=10ft

Step-by-step explanation:

Hey,

Since, the total height is 26, you add up the individual heights listed on the sides because they have to add up to 26.

So,

x+x+6=26 (From here it is basic algebra where you solve for x)

2x+6=26 (add the two x variables together)

2x=26-6 (subtract the 6)

2x=20 (divide by 2)

x=10 ft

The answer makes sense too because the line segments are larger than the segment 6 which was given.

If log10(x^{2}y^{3})=7 and log10 (x/y)=1 , then x=__ and y= __

yuradex [85]

Answer:

$x=100$

$y=10$

Step-by-step explanation:

we are given

$log_1_0(\frac{x}{y})=1$

Firstly, we will get rid of log

so, we will take exponent over 10 on both sides

$10^{log_1_0(\frac{x}{y})}=10^{1}$

now, we can simplify it

$\frac{x}{y}=10$

now, we can solve for x

$x=10y$

we are given

$log_1_0(x^2y^3)=7$

Firstly, we will get rid of log

so, we will take exponent of 10 on both sides

$10^{log_1_0(x^2y^3)}=10^7$

$x^2y^3=10^7$

now, we can plug back x from first equation

$(10y)^2y^3=10^7$

now, we can solve for y

$100y^5=10000000$

$\frac{100y^5}{100}=\frac{10000000}{100}$

$y^5=100000$

now, we can take radical 5

$y=\sqrt[5]{100000}$

$y=10$

now, we can find x

$x=10\times 10$

$x=100$

So, solution is

$x=100$

$y=10$
